TITLE 30.ENVIRONMENTAL QUALITY

Part 1. TEXAS NATURAL RESOURCE CONSERVATION COMMISSION

Chapter 114. CONTROL OF AIR POLLUTION FROM MOTOR VEHICLES

Subchapter H. LOW EMISSION FUELS

3. REFORMULATED GASOLINE

30 TAC §§114.322, 114.324, 114.326, 114.327, 114.329

The Texas Natural Resource Conservation Commission (commission) withdraws the proposal to adopt new §114.322 (Control Requirements), §114.324 (Registration of Gasoline Producers and Importers), §114.326 (Recordkeeping Requirements), §114.327 (Exemptions), and §114.329 (Affected Counties and Compliance Dates) based on an analysis of the comments received on this proposal. These revisions were proposed to Chapter 114 (Control of Air Pollution from Motor Vehicles), Subchapter H (Low Emission Fuels), new Division 3 (Reformulated Gasoline), and to the state implementation plan (SIP). The proposed new sections were published in the December 31, 1999 issue of the Texas Register (24 TexReg 11933).

The commission evaluated the comments received on the proposal to implement a state reformulated gasoline (RFG) program requiring gasoline which meets the federal Phase II RFG standards to be implemented in the additional eight counties making up the Dallas/Fort Worth (DFW) consolidated metropolitan statistical area. The additional counties that were proposed to be included are: Ellis, Henderson, Hood, Hunt, Johnson, Kaufman, Parker, and Rockwall Counties.

The commission received comments both in support of and in opposition to the proposal. Comments supporting the proposal were generally in support of additional controls to address air quality concerns. However, the majority of the comments opposing the proposal were in regard to concerns over water quality issues associated with the increased use of methyl tertiary butyl ether (MTBE) anticipated from expanding the RFG program to additional counties. Other opposing commenters questioned the legality of expanding the RFG program, requested additional controls on sulfur in gasoline, questioned the timing of the proposed implementation date, and requested that the commission adopt statewide clean fuel regulations instead of regional controls.

The commission's decision to withdraw this proposal is due in part to the concerns over water quality issues associated with the increased use of MTBE anticipated from expanding the RFG program. In its September 15, 1999 report, "Achieving Clean Air and Clean Water: The Report of the Blue Ribbon Panel on Oxygenates in Gasoline," United States Environmental Protection Agency's (EPA's) Blue Ribbon Panel on MTBE recognized the potential threat MTBE poses to water quality and recommended that the oxygenate mandate for RFG be removed and that clarification be provided on federal and state authority to regulate and/or eliminate the use of gasoline additives including MTBE. The commission supported the Blue Ribbon Panel's recommendations and understands that these issues are still under discussion. The commission will continue to closely monitor developments relating to the MTBE/oxygenate issues. Once these issues have been resolved, the state will reevaluate the necessity for additional gasoline control strategies in the DFW area.

The commission's decision to withdraw this proposal is also based on the EPA's new federal low sulfur gasoline regulations, which were finalized in December 1999, which require all gasoline, including reformulated and conventional gasoline, to meet a 30 part per million sulfur content standard beginning in 2004. These new federal gasoline rules will result in a low sulfur conventional gasoline that does not have the oxygenate requirement associated with federal RFG. In addition, since the DFW ozone nonattainment area is required to have three years of emissions monitoring data demonstrating the area's compliance to the national ambient air quality standard for ozone in order to support the 2007 attainment demonstration, the implementation of the federal low sulfur gasoline in 2004 should provide the DFW area the necessary time to allow the results of this program to be realized through air emissions monitoring data.
